Downconverters

Other Bands are available – Please contact BTS for more information.

All DTC receivers operating at frequencies above 850MHz require downconverters. DTC barrel downconverters are connected directly under the antenna and draw power remotely from the receiver. Downconverters are supplied as selectable high/low gain, which dictates how much cable they can drive (typically 10 – 15m for the low gain and 50 – 100m for high gain). For precise cable run length calculations contact BTS. DTC downconverters offer excellent low noise performance, are designed for permanent outdoor deployment and mounting kits are also available.

Dowconverter Barrel Gain Selectable Broadcast (DCBGSB)
The DTC selectable barrel down converter has optimum performance in all situations. It is easy to mount with magnetic, cable-tie and screw-hole fixings for maximum flexibility. LED indicator for gain (high/low/off). Powered from the receiver via co-axial cable (BNC) and connects to receiver via standard 75 Ohm cable.

The maximum length of cable depends on the RX frequency, as this dictates the down-converted UHF frequency which the cable has to carry. The theoretical cable lengths in the chart below show best and worst case, dependant on the frequency used:
